THIS!!! DD isn't a genius. He came into a good situation and was told to do whatever needed to take this team to a new level. I'm not even sure if how he did it is better than any other person could have done it. It's not hard to go out and buy the most expensive stuff when you can morgage the house.
And another thing I agree about, it's the fringe players GMs get that make or break a season. Pearce, Eovavaldi, Nunez, Napoli, Moreland. Correctly picking those kind of players is the true difficult task.
